Here X4 overplays high side, with his right foot in front of 5 and his left foot behind. 5 tries to step over X4's top foot to seal (lunge and seal), and stays low and wide, he does not want to stand up and look for a lob pass when overplayed. On a pass, X4 tries to knock it down or recovers if the pass is made, between 5 and the basket and getting off him. Don't try to steal the ball.
5 has three seconds to catch after posting up, and then one dribble, but can pass back out to 2 and re-post.
Progression - add another player on the weakside wing (or at the top), 5 can reverse pass and come across to post up.
